Truecrypt with Dropbox Automation ?

Hello Gurus,

Im being using Dropbox for some while now and I must say that I am really happy about it and I feel "secure" about my data being accessible without having to back it up...

But my concern is security and privacy.. Ive been reading about it and it seems that the combination truecrypt+dropbox is great since dropbox works on a byte diff sync so he doesn't upload the whole file again and again !!!
I tried it and created a truecrypt volume with 75Mb (for testing). the first time it took over 1 hour to sync. ( we have slow connection).
then when it was done..I opened that volume and added a small file (around 500k).
when I closed the volume I noticed that within 1-2 minutes the dropbox had finished.. So I am assuming that it works. !!! your comments are more than welcome here...

Now to my real problem...
Since using truecrypt is the solution ... I need to be able to automate it...
So what I need is a script that would open that truecrypt volume... mount it and copy the appropriate files to it and then close and dismount the volume so that the syncing can occur.

any idea how I can do this ?

thanks

Well you need a batchjob for that.

See also http://www.truecrypt.org/docs/?s=command-line-usage

Of cause you have to modify

driverletter "x"
archive file "C:\myData.tc"
source folder: "C:\My Project"
password: password

you can use any other command line sync tool. For parameters use

xcopy /? on command line

If I am to automate this , this is what I would need

1-Mount the volume using the proper command.

2-before copying the files (I would rather use robocopy) I need to make sure that the volume was mounted... How Can I check for that ?
Maybe look for a specific file in that volume ?

If exist % FILE... then proceed else ..error

please help

you could use the "pause" command in the batchfile.

Robocopy is fine, using the parameter /MIR will mirror source and target.

---
Just seeing the original code is gone...

Tolomir

echo off
truecrypt /v myvolume.tc /lx /a /p MyPassword /q
if not exist x:\donotdelete.txt goto close
pause
robocopy C:\source X:\mirror /MIR
echo Transfer done
pause
truecrypt /q /dx 
:close

Open in new window

You might want to do some more testing to make sure that Dropbox always identifies file changes in the TC file. I had a 4GB TC file and, while I didn't try it with Dropbox, my backup provider Backblaze didn't appear to notice certain small changes.

See: Dropbox will always notice when anything has changed inside your Truecrypt file. Dropbox uses the same mechanisms as for any other file. The same advantages of byte-level synchronization apply.
